Portability problems not fixed by Gnulib:

  * This function is missing on some platforms: mingw, BeOS.

  * Some older versions of glibc had nl_langinfo but not the CODESET macro.

  * On Cygwin 1.5.x, which doesn't have locales, nl_langinfo(CODESET) always returns "US-ASCII".

  * On Cygwin 1.7.0, only the charset portion of a locale designation is honored.
